How to check if a number is prime prime numbers are divisible only by themselves and 1 all other numbers are called composite numbers there are numerous ways to test whether a number is prime, but there's a trade off. Prime: prime, any positive integer greater than 1 that is divisible only by itself and 1—eg, 2, 3, 5, 7, 11, 13, 17, 19, 23, a key result of number theory, called the fundamental theorem of arithmetic (see arithmetic: fundamental theory), states that every positive integer greater than 1 can be.
Get answers to your questions about prime numbers with interactive calculators see if a number is prime, make a list of primes, do prime factorization, find classes of primes. To find out a prime's multiples we can either a test each new candidate number for divisibility by that prime, giving rise to a kind of trial division algorithm or b we can directly generate the multiples of a prime p by counting up from it in increments of p, resulting in a variant of the sieve of eratosthenes.
